China polysilicon prices in freefall
In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.
Canadian Solar announces 5 GW US module factory
Representing an investment of $250 million, the facility is expected to bring 1,500 jobs.
Perovskite solar cell based on indium sulfide ETL promises 20.15% efficiency
An international team has sought to use indium sulfide as an electron transport material in a perovskite solar cell. The result is a device with lower defect density and improved performance.
Longi claims 33.5% efficiency for perovskite/silicon tandem solar cell
The European Solar Test Installation (ESTI) has confirmed the results of Longi’s new perovskite/silicon tandem solar cell. It is currently the second-highest efficiency record in the world for a perovskite/silicon tandem cell.
CubicPV secures $103 million of support for US wafer manufacturing
CubicPV says it plans to establish 10 GW of conventional mono wafer manufacturing capacity in the United States, driven by incentives in the US Inflation Reduction Act. The wafers could fill a void in the domestic supply chain and create 1,500 new direct jobs.
Chinese PV Industry Brief: Q-Sun Solar expands module capacity by 12 GW
Q-Sun Solar says it plans to invest CNY 6.2 billion ($865.6 million) to build 10 GW of solar cell capacity and 12 GW of PV panel capacity.
Treatment promises 1000-hour stability for solar perovskites
Scientists in China and Canada have developed an additive that forms covalent bonds with the organic materials in a perovskite solar cell, leading to fewer defects and greatly reduced degradation. Cells treated with the additive maintained 98.6% of their initial performance after 1,000 hours in testing. Xlynx Materials, a company spun out of the University of Victoria in Canada, is making the material available for further commercial trials.
Reducing solar module temperature with acrylic sheets
Jordanian researchers have developed a method using acrylic sheets to reflect and absorb unused solar radiation in PV power generation. The solution has the potential to decrease solar panel temperature by more than 14% and increase power yields by approximately 2%.
Potential benefits and challenges of PV-powered vehicles
The extent to which PV-powered vehicles contribute to a reduction of CO2 emissions depends on variables such as the carbon intensity of the local grid, driving patterns, and solar irradiation. The market introduction requires technical optimization of the PV, but also of the vehicles.
Wavelabs launches LED-based flashers for module manufacturers and R&D lab
The German PV testing equipment provider said its new Sinus-3000 Pro line is an ‘all-in-one system’ that can perform power measurements, bypass diode testing, insulation testing, visual inspection, and electroluminescence measurements. It is also offering the Sinus-3000 Advanced line for the testing of perovskite-silicon tandem, multi-junction and other new material cells.
